Abstract
In a first printing process in Steps S through S , ink supply is controlled so that a measured printed density (Vn) is approximately equal to a first target density (V ). This provides a uniform amount of ink remaining on ink rollers after the first printing process. Thereafter, in a second printing process in Steps S through S , printing is performed using a second target density (V ) lower than the first target density (V ). This provides a slightly reduced, uniform amount of ink remaining on the ink rollers. Thus, a novel method of presetting ink is provided which facilitates the formation of a distribution of the new amount of ink at the beginning of the next printing operation and which stabilizes the early start of printing.
